Putoline air filters, based on leading edge open-cell foam technology, bring users major benefits, including:
– Improved performance through increased airflow
– Improved protection through finer filtration levels
– Substantial cost savings through serviceability and re-use
Fully reticulated (open cell) foam, as used in all Putoline filter products, consists of a honeycomb of tiny, interlocking cells of uniform size. When treated with specially formulated filter oil, each passageway is like hundreds of very small centrifugal/oil bath filters connected one to another. In this way, the foam traps and holds the particles throughout the entire volume of foam.
The development of this unique foam represents a major advancement in air filtration technology. As a result, foam air filters, when compared with paper or cotton gauze equivalents, combine great airflow capability, huge dust holding capacity, and very high filtration efficiency for even extremely small particles.
|Coarse open-pore foam catches airborne dirt, grime and sand.|
|Fine open-pore inner foam acts as a second filter to trap the smallest particles while ensuring maximum air passage.|
|Exclusively formulated adhesive ensures glue seams will not break down.|
|Thick, flat foam, greaseless sealing ring ensures maximum contact with your airbox, while acting as a breathable gasket for increased air passage.|
|Fused outer and inner elements prevent dirt and grime from being lodged between layers, unlike Twin Air, this can be a problem with inferior two-piece designs. Trapped particles can restrict airflow. And if dirt works it’s way into your engine, a pinhead-sized granule will gouge your used-pre-oiled-air-filter-smallcylinder, piston and rings like a bullet.|
